According to the 2000 U.S. Census, North Dakota counties that include Indian reservations are among the few areas of the state to experience population increases. Normally, the age distribution of a population is important when determining the labor supply in the area. Age distributions generally do not change significantly in the short-term unless large population changes have occurred in the area. With the growth of economic activity generated by the establishment of casinos and other economic ventures associated with industry and business, population statistics show steady increases as Indian people return home.
The tribal headquarters of the Three Affiliated Tribes was built in 1979 and is located four miles west of New Town on state Highway 23. The main communities on the reservation are experiencing growth in the commercial, industrial, and business sectors. The government sector, consisting of the Bureau of Indian Affairs, administration of the Three Affiliated Tribes and its enterprises and Indian Health Services, is still the major employer on the reservation. Residents travel to Bismarck, Dickinson, Minot or Williston for wholesale shopping. Railroad, commercial, and charter air transportation services are available in Minot and Bismarck, North Dakota. New Town and Parshall have landing strips for smaller aircraft.
